Error enumerating smb shares

Describe the bug Every time I try to enumerate smb shares cme crashes. I tried manual installation and docker container.

To Reproduce & stacktrace execute this command:

crackmapexec smb --shares <ip>
SMB         <ip>      445    <computer-name>          [*] Windows 6.1 (name:<computer-name>) (domain:<domain>) (signing:False) (SMBv1:True)

**Expected behavior**
List of smb shares being returned

**Crackmapexec info**
 - OS: Arch linux (5.10.5-arch1-1)
 - Version of CME: 5.1.1dev
 - Installed from [AUR](https://aur.archlinux.org/packages/crackmapexec/)

**Additional context**
SMBclient is able to enumerate the smb shares
